Why do Postcodes Change?
The Postcode system is dynamic - it changes frequently with around 1.25 million address changes in an average year. There are times when Royal Mail are forced to make changes to the Postcode system in order to maintain postal delivery efficiency.
For example, new housing developments or business parks in already densely populated areas can leave no free postcodes for Royal Mail to allocate. this can lead to the recoding of a wider area to create additional codes to allocate.
Update Frequency
Royal Mail are continually updating the national address database but they release Postcode update summaries every 6 months which provide broad details concerning which areas have been affected. See below for the latest Postcode release information.
Map-Logic provide updates to all associated databases and tables every 3 months to help ensure your data content is as accurate and up-to-date as possible.
